Take the following steps to start a project:

1. Start Visual Studio .NET.
2. Choose File->New->Project… from the menu.
3. In the New Project dialog box, Choose either "Visual C# Projects" or "Visual Basic Projects" in the Projects Type List, and choose "Windows Application " in the Templates List.
4. Type the project name as "Splitting Multi-page TIFF file" in the Project Name field, and then click OK. If desired, type a new location for your project or select a directory using the Browse button, and then click OK .
5. In the "Solution Explorer" window, right-click on the "References" folder, and select "Add Reference…" from the context menu. In the "Add Reference" dialog box, select the ".NET" tab, browse to the "C:\LEADTOOLS 19\Bin\DotNet\Win32" folder, and select the following DLLs:
   • Leadtools.dll
   • Leadtools.Codecs.dll
   • Leadtools.Codecs.Fax.dll
   • Leadtools.Codecs.Tif.dll
   Click the Select button and then press the OK button to add the above DLLs to the application.
6. Go to the toolbox (View->Toolbox), drag and drop a Button control on the form, and set the following properties for it:

   Text	Name
   Split TIFF	buttonSplit

7. Switch to Form1 code view (right-click Form1 in the solution explorer then select View Code) and add the following lines at the beginning of the file:

   [Visual Basic]

   
               Imports System.IO
               Imports Leadtools
               Imports Leadtools.Codecs
               Imports Leadtools.ImageProcessing
               
   

   [C#]

   
               using System.IO;
               using Leadtools;
               using Leadtools.Codecs;
               using Leadtools.ImageProcessing;
               
   

8. Add an event handler to the buttonSplit Click event and code it as follows:

   [Visual Basic]

   
               Private Sub buttonSplit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles buttonSplit.Click
                  ' Intitialize a new RasterCodecs object.
                  Dim codecs As New RasterCodecs()
                  Dim multiPageFileName As String = CreateMultiPageFile(codecs)
                  ' Find out how many pages the file has
                  Dim info As CodecsImageInfo = codecs.GetInformation(multiPageFileName, True)
                  ' Loop through the pages of the file; perform specific processing on it, then save each page to a separate file:
                  Dim flip As New FlipCommand()
                  Dim outputDir As String = "C:\Users\Public\Documents\LEADTOOLS Images"
                  For pageNumber As Integer = 1 To info.TotalPages
                     ' Load the next image in the loop
                     Dim image As RasterImage = codecs.Load(multiPageFileName, 0, CodecsLoadByteOrder.BgrOrGray, pageNumber, pageNumber)
                     ' Perform specific processing on the page, such as flipping it
                     flip.Run(image)
                     ' Save the page to a separate file
                     Dim pageFileName As String = Path.Combine(outputDir, "Page" + pageNumber.ToString() + ".tif")
                     codecs.Save(image, pageFileName, RasterImageFormat.Tif, 0)
                  Next
               End Sub
               
   

   [C#]

   
               private void buttonSplit_Click(object sender, System.EventArgs e)
               {
                  // Intitialize a new RasterCodecs object.
                  RasterCodecs codecs = new RasterCodecs();
                  string multiPageFileName = CreateMultiPageFile(codecs);
                  // Find out how many pages the file has
                  CodecsImageInfo info = codecs.GetInformation(multiPageFileName, true);
                  
                  // Loop through the pages of the file; perform specific processing on it, then save each page to a separate file:
                  FlipCommand flip = new FlipCommand();
                  string outputDir = @"C:\Users\Public\Documents\LEADTOOLS Images";
                  for(int pageNumber = 1; pageNumber <= info.TotalPages; pageNumber++)
                  {
                     // Load the next image in the loop
                     RasterImage image = codecs.Load(multiPageFileName, 0, CodecsLoadByteOrder.BgrOrGray, pageNumber, pageNumber);
                     // Perform specific processing on the page, such as flipping it
                     flip.Run(image);
                     // Save the page to a separate file
                     string pageFileName = Path.Combine(outputDir, "Page" + pageNumber + ".tif");
                     codecs.Save(image, pageFileName, RasterImageFormat.Tif, 0);
                     image.Dispose();
                  }
               }
               
   

9. Add the following code to the Form1 class:

   [Visual Basic]

   
               Function CreateMultiPageFile(ByVal codecs As RasterCodecs) As String
                  ' Create a multi-page TIF file
                  Dim pageFileName() As String = _
                  { _
                     "C:\Users\Public\Documents\LEADTOOLS Images\Ocr1.tif", _
                     "C:\Users\Public\Documents\LEADTOOLS Images\Ocr2.tif", _
                     "C:\Users\Public\Documents\LEADTOOLS Images\Ocr3.tif", _
                     "C:\Users\Public\Documents\LEADTOOLS Images\Ocr4.tif" _
                  }
                  Dim image As RasterImage = Nothing
                  For i As Integer = 0 To pageFileName.Length - 1
                     ' load the page image
                     Dim page As RasterImage = codecs.Load(pageFileName(i))
                     If (i = 0) Then
                        ' first image, just save it into our variable
                        image = page
                     Else
                        ' add this page into our image
                        image.AddPage(page)
                        ' we do not need this page anymore
                        page.Dispose()
                     End If
                  Next
                  Dim outputFileName As String = "C:\Users\Public\Documents\LEADTOOLS Images\MultiPage.tif"
                  If (File.Exists(outputFileName)) Then
                     File.Delete(outputFileName)
                  End If
                  codecs.Save(image, outputFileName, RasterImageFormat.Tif, 1, 1, 4, 1, CodecsSavePageMode.Overwrite)
                  image.Dispose()
                  Return outputFileName
               End Function
               
   

   [C#]

   
               string CreateMultiPageFile(RasterCodecs codecs)
               {
                  // Create a multi-page TIF file
                  string[] pageFileName =
                  {
                     @"C:\Users\Public\Documents\LEADTOOLS Images\Ocr1.tif",
                     @"C:\Users\Public\Documents\LEADTOOLS Images\Ocr2.tif",
                     @"C:\Users\Public\Documents\LEADTOOLS Images\Ocr3.tif",
                     @"C:\Users\Public\Documents\LEADTOOLS Images\Ocr4.tif"
                  };
                  RasterImage image = null;
                  for(int i = 0; i < pageFileName.Length; i++)
                  {
                     // load the page image
                     RasterImage page = codecs.Load(pageFileName[i]);
                     if(i == 0)
                     {
                        // first image, just save it into our variable
                        image = page;
                     }
                     else
                     {
                        // add this page into our image
                        image.AddPage(page);
                        // we do not need this page anymore
                        page.Dispose();
                     }
                  }
                  string outputFileName = @"C:\Users\Public\Documents\LEADTOOLS Images\MultiPage.tif";
                  if(File.Exists(outputFileName))
                     File.Delete(outputFileName);
                  codecs.Save(image, outputFileName, RasterImageFormat.Tif, 1, 1, 4, 1, CodecsSavePageMode.Overwrite);
                  image.Dispose();
                  return outputFileName;
               }
               
   

10. Build, and Run the program to test it.
